l DEEP-WELL PUMP.-

sPEcrFrcA'rroN forming part of Letters Patent No. 737,928, dated september i, 190s'.

Application filed February 26, 1903. Serial No. 145,l44.' (No model.)

To all whom it may concern:

Be it known that I, N ILS AUGUST HEYMAN, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Deep-Well Pumps, of which the following is a full, clear, and exact description.

This invention relates to certain novel and useful improvements in pumpsand has particular relation to a pump for raising water from deep Wells, mines, or the like by means of compressed air.

In carrying out the present invention I have particularly in View the construction of an apparatus through the medium of which a steady regular iow of water from the'well or mine will be maintained, such apparatus also embodying the essential and desired features of simplicity and durability.

A further object of the invention is to provide a pump with a series of chambers having therein a suitable valve mechanism and to provide passage-ways for the water to be elevated from the well, so that said valve will alternately close the air-passages and the water-passages at stated intervals.,

With these and other objects of a similar nature in View my invention consists in the construction, combination, and arrangement of parts as is described in this specification, illustrated in the accompanying drawings, and set forth in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the igures.

Figure 1 is a longitudinal sectional View taken through a well, my improved pump being shown therein in elevation. Fig. 2 is a central vertical sectional view taken through the upper chamber and showing the arrangement.

of the piston-valve and float therein. Fig. 3 is a similar View taken through the lower enlarged chamber of the pump, showing the arrangement of the Water-inlet, the bottom of the well, and the arrangement of the valves therein. Fig. 4 is a vertical sectional View taken on the line .r ot' Fig. 3. Fig. 5 is a sectional View on the line y 'y of Fig. 2, and Fig. 6 is a sectional View on the line .a .a of Fig. 5.

Referring now to the accompanying draw-l ings in detail, A designates a well in which is inserted my improved pump.

As will be seen, the pump comprises the relatively long body-casings 1, 2, and 2a, which lead upward to a point of discharge 3. The construction and arrangementvof the various tubes, casings, and chambers will be clearly seen in Figs. 2, 3, and Il. In Fig. 3, it will be seen, at the bottom of the pipe or casing 1 there is formed a housing or water- 'chamber et, an opening 5 in the bottom of the chamber being controlled by the disk valve 6. Avalve-seat 7 is formed transverselycentrally ofl this housing 4, upon which valveseat is adapted to rest an annular Hangevalve 8, formed at the bottom of a collar 9, which slides upon the cylindrical tubing 10, arranged concentric-ally within the casingsection 1, a'chamber being formed between said casing-section and the tubing 10. At the upper end of the casing-section 1 is arranged an enlarged chamber 11, having an .orifice or bore 12 extending entirely through the same. Arranged above this bore or oritice is a valve-seat 13, designed to form a bearing for the disk valve 14, which is similar in construction to the valve 6. From the upper portion of the chamber 11 extends the casing-section 2, and Within said section is arranged a cylindrical tubing 15, which is similar to the tubing 10 and has a flanged collar-valve 16 slidably mounted thereon, the lianged portion of which valve is adapted to rest upon the seat 17.

Connecting the portion 2 of the Wellcasing with the portion 2a, extending above the same, is an enlarged chambered portion 18, similar in shape to the chamber 11, this chamber 18 having an enlarged vertical extending bore 19, which communicates with the casing 2, and a reduced vertical bored portion 20, communicating with the tube 15 through the medium of a small port 21.

From the upper surface portion of the well and into the chamber 18 leads an air-pipe 22, and an air-duct 23, extending vertically parallel with the enlarged bored portion of said chamber, is turned parallel, as at 24, to communicate with the reduced bored portion 20, heretofore mentioned. A second passage- IOO way 25 communicates with this reduced bored portion, and through a pipe 26 air is carried to the vertical passage-way 27, formed in the lower chamber 11, said passage-way being turned or goosenecked, as at 28, to communicate with the tubular chamber 10.

From the construction thus far described it will be seen that air passing in through the pipe 22 enters the small reduced bored portion 20, from which portion it passes through the pipe 26, through the duct 27, and into the water-tube 10. Water is at this period supposed to have filled the chamber 10, which chamber contains a float 29. The compressed air pushes down the float 29 and closes the Valve 6 at the bottom of the housing 4, at the same time opening the collar-valve 8, and the water passes up in the space between the tube 10 and the casing 1 'and enters the chamber 11, from whence it rises to the discharge-pipe3. When the float 29 is at the bottom of the tube or cylinder, it acts to prevent the air escaping in the water-discharge. In the meantime the tube or cylinderhas lled with Water entering the opening 12 of the chamber 11, and the pressure of iuid causes the valve 14 to be lifted from its seat, and simultaneously a oat 30, which slides freely upon a piston-rod 31, is elevated and moves Vupward the piston-valve 32. When the piston-valve is thus raised, the air-inlet port will be opened to the exhaust 33 and air from the port 24 will pass through the inside of the piston-valve 32 into the port 21 and will force down the water and the oat in the cylinder 15. The piston-valve is maintained'in its upright position through the means of spring clamping-arms 34,which clamp a ring 35 upon the piston-rod 3 1. At the upper portion of said rod 31 is mounted a counterweight 36, suspended by chains 37 and passing over pulleys 38, the springs, counterweight, chains, and pulleys being encased in a housing 39. When the pistonvalve is in its elevated position and the air is exhausting through a passage 33, the water from the well will again rise in the lower Water-tube until the float 29 is raised against the air-inlet 28, and the entrance of water will be prevented. In the meantime the pressure of air in the cylinder 15 has forcedv theV water therein down until the float 30 strikes a collar 40 at the end of the valvestem and pulls the piston-valve down again, permitting the air to enter through the intake 22 and 26, as before described.

From the above description it will be seen that I have provided an exceedingly simple pump and one which is especially advantageous for use in mines or in very deep Wells. For shallow wells the cylinders and discharges may be larger in diameter and may be placed side by side instead of one above the other, as in the present instance, and under some circumstanoes it may also be desirable not to have the cylinder inside of the dischargevalve; but the principle of the invention will not be effected by these changes.

While I have shown and herein described one particular embodiment of my invention, I wish it to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in some respects without departing from the principle of the invention or sacrificing any of the advantages thereof.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent- 1. The combination of a casing,a fluid-chamber within said casing, a valve mechanism for con trolling the admission of fluid to the chamber, a piston-valve movable vertically at predetermined times for controlling the admission of air to the chamber, a housing mounted above the piston-val ve into which housing the rod of the piston-valve extends, and a counterweight mounted on the piston-rod and suspended from chains passing over pulleys in the housing and connected to the pistonrod, substantially as set forth.
